A Solider Huh?

"Teaching is like a solider on the front lines in a battle." This is what my SBTE told me the other day. I'm not really sure I agree with her though. I do agree that teaching is hard, but a solider in battle? There are things a solider goes through on the battle field that no one else can even imagine unless they've been there themselves. Who's to say that a teacher has a harder job than a farmer? Every job has it's difficulties and each difficulty is different than the next.
